Greetings to all. I'm new to the Omega forums and need some help. I recently came into a Vintage Omega men's manual wind watch. It's in very good condition and operates perfectly. I don't know and can't find are the details on the model, type of movement and specifications. The serial # 10643300 indicates it was made in 1944. The caseback has the
# 2735-1SC. That's the only info I have found. I would be very grateful for any help with this information. I want to thank you all in advance.
Sincerely Paul

 

Welcome, Paul. 2635 is the reference number. The serial is more likely 1945-46 (the standard chart suggests that 10M-11M refers to the 1944-47 period, and yours is in the middle of the range), but that's just a quibble. I believe the movement is in the 30mm family, but the "SC" on the case-back usually refers to center-second and it doesn't appear to be a center seconds movement at first glance. Perhaps you can also show the dial and the rest of the case.

 

The Omega vintage database says the 2735 was made 1954-1958. Is it possible that a movement made in 1946 would have originally be put in a case made in 1954?

I also noticed the 2735 should have a cal 420, which the original watch doesn't have?



Perhaps the caseback was swapped?

 

Not likely.

Makes sense, it needs a center-second movement.

At least the case-back.

 

The movement is a caliber 28 17P.
Haven't checked anything else yet.

Oh, and the hairspring!

 

But it operates perfectly!

 

Dan, I can't thank you enough for your greeting and especially sharing your expertise. As you have confirmed, the movement was made in 1944. I have also discovered from others that the reference number, 2735-1SC indicate
the watch, or the caseback, being from
1954-58.

 

Gentlemen, Dan S., Wagudc, and
JimiOZ, thank you for the warm welcome and making me feel at home. I can't begin to thank you all enough for taking the time to reply and comment on my watch. I apologize for my slow reply. I've been recovering from surgery. The watch seems to be somewhat of a mystery. It seems strange but possible that someone put the older movement into the case. I have included photos of the watch. They may help to explain something new or confirm what you already know.
Thanks in advance for your help.
Cheers Paul

 

To put it clearly, I think it's a "parts" watch where somebody had a case and a movement, they put them together with a re-painted dial to look like a "military" Omega.
Luminous marker but no hand lume?
Apart from the obvious "pseudo-military" style of dial, the Ω symbol is from much later than other parts of the watch.

You don't say how you came into the watch.
If you purchased it recently you should return it if it doesn't fit the description it was sold under.

 

I hope that your recovery from surgery is going well.

Just to elaborate on @JimInOz's post. The case-back is for a 2735, but the mid-case is not a 2735. I'm not sure what reference the mid-case belongs to, looks like possibly one of the chunky lug Seamasters. The dial is what we call a "fantasy redial", not corresponding to any particular model. As a whole, the watch has been creatively assembled from parts. If it gives you joy, that's not a problem and you can just enjoy wearing it. However, as Jim noted previously, the movement doesn't look like it's in great shape, so you may find yourself in a position where you need to pay for repairs.

 

I hope you stick around, and recover from the surgery as quickly as possible. You can learn a lot from the folks here like @Dan S and @JimInOz. I have picked up a bit, and share what I know when I can. The knowledge some of the members here possess boggles the mind.
